Well, the trims are there for more than just esthetic reasons. They are holding the tank together and preventing the tank from falling apart after you add 150 gallons of water. Under pressure, the joints will come loose and there is 99% chance that the front and/or rear pane will blow out. You are looking at, roughly, 1500 LBS of water if you make it a SW
tank. So, no, you should NOT remove the trimming. Adjust your DIY
stand and canopy to merely hide the trims if you really cannot live with the sight, or get an acrylic tank.
